WARNING

Please carefully read all the instructions given in this booklet, as they’ll be all very useful for both safe installation and proper use & maintenance operations.

Installation is to be carried out always strictly complying with the current standards of the country where the appliance is going to be used and following, of course, the instructions given by the maker. Only skilled operators and Authorised

Assistance Centres will be entitled to carry out installation. Please note that, should wrong installation cause harm to people or damage things, in no way the manufacturer will be held responsible for it.

Before opening, check well packing cardboard box and its contents. If any doubt, don’t use the unit but contact the supplier first.

Always keep packing parts away from children reach, as they may be harmful.

Keep suction grids clear.

In case of breakdown or failure: turn unit off, do not try to repair it on your own, call operator.

If you are going to leave the generator off for a long time, first make sure that in no way this could cause harm to anyone in any way.

This unit was designed to be used for heating purposes only. Any different use is not allowed as it may be dangerous.

Always keep this handbook with the unit.

Should the unit work in a house where disabled people and/or children live, it must be placed safely away from their reach. Always make sure that the access door to the inside control board stay locked.

GAS ESCAPE

In case of typical gas smell, do not turn on electric switches nor use telephone or any other appliance that could produce sparkles. Quickly open doors and windows to let fresh air in, lock the gas detecting hand-valve and call for qualified operator.

PERFORMANCE

The “K X” hot air hanging generator is an appliance that heats room air by exploiting the thermal energy resulting from combustion. This thermal exchange is obtained by a no-stop air jet lapping the heat-exchanger areas. The air jet comes from a centrifugal fan, without need of intermediate fluid. Thanks to their high heat performance (> 90%), safe working, low noise level, quick setting-up, the “K X” series units are the best for industrial plants, warehouses, gyms, greenhouses, swimming pools, and so on (however they should never work in places directly subject to atmospheric conditions).

GENERAL MANUFACTURING FEATURES

HEAT EXCHANGER ( 4 SMOKES REVOLUTIONS)

Made of welded stainless steel sheet, sealed tested to meet the current European standards, easy to check for standard cleaning and maintenance operations: a) Combustion chamber made of Aisi 430 stainless steel sheet, circular section, of suitable thickness and volume. b) Wide surface exchanging elements made of low thermal load high quality stainless steel, rhomboid section, granting lower resistance to air cooling and improved thermal efficiency. c) High quality stainless steel rear smokes collector, with wide inspection door for easy checking and cleanings of the exchanger. d) High quality stainless steel front smokes collector, which opening is closed by safety disk of suitable features, acting as overpressure valve.

8

OUTER CASING

No visible panel fixing parts : this gives the machine a new fashionable look, while enabling very easy checking too. The outer casing is made of removable panels made of pre-varnished galvanised sheet, with an upper protective film.

The burner housing is totally sealed with respect to the room. Checking door.

The areas the most subject to radiant heat by the exchanger are provided with noise and heat proof insulation

Baffle for air flow direction, double range of vertical and horizontal wings, each one adjustable to improve even air flow diffusion.

VENTILATION UNIT

It is made of two low noise centrifugal fans, with built-in engine, granting great air delivery. They are provided with mesh safety panels for accident prevention.

BURNER UNIT

It’s made of:

- Hooking plate with peep-hole to check electrodes and flame.

- Certified blow type burner, gas or gas oil working (option on request).

CONTROL AND SAFETY THERMOSTATS

The generator is provided with three thermostats which are already assembled and electrically connected, as follows :

"Fan" thermostat, liquid expansion type. It starts up the fans when average air temperature is approx. 40°C, to avoid cool air getting into the room, then it turns them off when burner goes off, when the temperature raises to 40°C.

“Limit” thermostat, liquid expansion type. It stops the burner when the average air temperature gets approximately over 80°C.

“Maximum” thermostat, hand reset, liquid expansion type: it definitely stops burner in case of anomalous air overheating. If necessary, you can reset it by hand by pressing the key, however only after detecting and removing the reason of such anomalous behaviour.

OPTIC SIGNALLING UNIT

Green light, to show correct working.

Red light, it shows any electronic board blockage.

OPENING for SMOKES EXHAUST

The combustion products are exhausted outside through a round opening on the appliance, to be connected to a metal pipe in the permanent way.

This pipe must be sized as follows :

It must have wider or same diameter than the opening , with no section reduction..

Smooth inside surface. If wrinkled flex pipe was to be used, first make sure that the increased loss of load would not involve “unhealthy” combustion conditions and too much of a counter-pressure inside the combustion chamber. Please check the burner’s working field in the attached manual.

With the C13 and the C33 types the length must not exceed 4 m. (please remember that an elbow is equal to approx. 0.8-

1 m. of straight pipe).

With the C53 and the B23 types, please remember that the length must not exceed 6 m. (please remember that an elbow is equal to approx. 0.8-1 m. of straight pipe).

COMBUSTION AIR INLET

The combustion air gets in through a circular opening, protected by a net made of meshes smaller than 16 mm..

If the appliance was installed in a place with no air intakes from outside, the combustion air intake too must be connected to the outside, to grant a “sealed chamber” performance.

The same has to be done in case of an “under depression” room, or a dusty room, to avoid any anomalous working of the burner or the flooding of it.

The installation system length must not exceed 4 m. ( keeping in mind that each elbow is long about 0,8-1 Mt. of straight pipe) and should be provided with an outside protecting terminal top the obstruction section of which must not be wider than

40 cm

2

.

FLUES

All flues have to be made complying with the standards of the country where the generator is going to be used

Every appliance should be provided with its own flue.

The minimum diameter should never be under 220 cm

2

.

Every flue should be provided on the bottom with a special chamber for collecting and exhausting the liquid waste stuff.

With gas oil working appliances always remember that the flue width must never be smaller than the joint to the chimney. We recommend in fact to make the flue a 15-30% bigger, and well refined.

9

With gas working appliances, the flue diameter must be long 4 cm

2

per each installed power kW.

The flue must be insulated so that the temperature will decrease less than one degree per meter.

The chimneys openings must exceed one meter the top of roof, parapet or any obstacle standing at least 10 meters away.

OPTIONS FEATURES - upon request

To make the generators installation easier, the following options are available : ducts, elbows, windproof terminals for air

suction and smokes exhaust. Just specify required pieces and sizes when ordering.

Adapter:

made of galvanised steel sheet : by this one flue diameter and combustion air suction opening can be adjusted to fit any size available in Europe, as required by the EN 303-3 rule of 1996.

Shelves :

made of painted pressed stainless steel. Wall hooking plate.

Fireproof shutter for air recycling and delivery (REI 120 certified) : it stops the generator air delivery and suction circle, when the temperature is over than required. It is made of a rotating blade made of cardboard plaster, some blade rabbet fillets in the shut position, a control device including a set/reset lever, a return spring, a magneto-thermal switch with fuse being set at 70°, and a galvanised stainless steel supporting structure with 40 mm flanges . Ready for canalisation connection : we recommend to set a micro-switch connected online to the burner, so to open the circle when the shutter is working.

SHIPPING & PACKAGING

Our KX wall hanging appliances are delivered on pallet; accessories are packed separately.

Shipping, unloading and handling of the goods are all operations to be made very carefully in order not to damage goods : always handle the appliance from the bottom only.

INFORMATION for SKILLED INSTALLING OPERATORS

Install the appliance strictly complying with the rules in force in your country

!

When choosing the place where to install the unit please keep well in mind the following points :

♦

The appliance must never be placed inside wall recesses

♦

It must be fixed 2,5-3 Mts. up the floor, so that the air flow would not be shot onto the people in the heated area

♦

Always grant easy connection to the fuel mains

♦

Always grant easy connection between appliance and smokes exhaust and combustion air suction pipes

♦

If required by law, make necessary ventilation holes

♦

The working temperatures field must be between – 5°C and + 40° C

♦

There must be no obstacles too close to the generator as this would affect the proper hot air diffusion, complying with the current laws and safety rules in gas operated thermal plants

♦

The generator is usually placed on wall hanging shelves ( the leaning point must only be the bottom of the appliance) to be conveniently fixed to a suitable structure, keeping the minimum distances from walls and ceilings, in order to :

- grant the safe recycling of the air to be heated;

- make cleaning and maintenance operations easier;

- avoid depression that would rise in case the appliance was too close to ceiling and wall, which would inhibit the correct air cooling inside the combustion chamber.

♦

In case holes were made across flammable walls, please note that an insulation must be provided around the smokes exhaust of the size of 5 cm at least.

Please note: - Before installing the unit, make sure with the Local Gas Supplying Agency that the maximum gas capacity is actually available for the unit, and that mains pressure and kind of gas are compatible with the data stated in our

Technical Data Table here above.

MAINTENANCE PARTS.

INFORMATION FOR THE USER

This appliance has been designed to be used on industrial plants, trade buildings, artisan workshops, warehouses, gyms, hothouses, pools, and many other public places, except for homes. Also, never use it in open-air.

WORKING STAGES

Put main switch on (if any).

Open gas or gas oil tap.

Schedule room thermostat at the required temperature.

The appliance now becomes automatic in all its functions.

The burner starts and, after a pre-washing time, it starts running. A few minutes after burner’s start, fan will start working too, blowing hot air into the room.

As soon as room temperature will raise to the figure scheduled on room thermostat, burner will stop and - about 4 minutes later - fan will stop too.

This full cycle will be automatically repeated from the beginning, every time room temperature goes below the temperature scheduled on the room thermostat.

STOP or TEMPORARY STOP

To stop the appliance, just turn off room thermostat switch or summer/winter switch if any.

WARNING : DON’T CUT OFF VOLTAGE WHEN THE APPLIANCE IS HOT AND THE FAN WORKING. This because the thermal energy stored inside the exchanger would activate the safety “LIMIT” thermostat, so it would become necessary to reset it by hand. Also, this wrong operation would involve overheating to the heat exchanger.

REST AT THE END OF THE COLD SEASON

When the cold season is over, take current off definitely, by depressing the main switch.

Shut gas or gas oil tap.
